A board full of gears. Can you get them all turning?
Tap a gear to select it, then tap where it should go. Gears spin when they connect to a matching color, and stacked gears turn if either of their colors matches a neighbor. Different colors can overlap and still spin.
Locked gears can't be moved, so build a path of other gears to reach them and set them spinning.
